使用正则表达式查找对象的值

Question

I am trying to find the values of a JavaScript object using Regex.

Sample object: classes: {wrapper: 'sm-mb--1-half md-mb--2', item: 'sm-mb--quarter sm-mt--quarter'}

Expected output: sm-mb--1-half md-mb--2 sm-mb--quarter sm-mt--quarter

What I have so far /\\{([A-Za-z]*:\\s'.*',?\\s?)*\\}/gm , but for some reason it selects everything..

Using lookahead and Lookbehind you can achieve what you want.

 let str = `classes: {wrapper: 'sm-mb--1-half md-mb--2', item: 'sm-mb--quarter sm-mt--quarter'}`; const regex = /(?<={.*:).*?(?=,|})/g; console.log(str.match(regex))
